Abstract

Interpolatory necessary optimality conditions for H2\mathcal{H}_2-optimal reduced-order modeling of non-parametric linear time-invariant (LTI) systems are known and well-investigated. In this work, using the general framework of L2\mathcal{L}_2-optimal reduced-order modeling of parametric stationary problems, we derive interpolatory H2L2\mathcal{H}_2 \otimes \mathcal{L}_2-optimality conditions for parametric LTI systems with a general pole-residue form. We then specialize this result to recover known conditions for systems with parameter-independent poles and develop new conditions for a certain class of systems with parameter-dependent poles.
